Space junk is a major problem that we need to deal with right now and scientists have proposed many solutions to deal with this issue. One of them is to grapple and remove space junk from key orbits around Earth with a space tug using magnetic forces.
Scientists have been researching how the resulting guidance, navigation and control techniques would work in practice, combining a rendezvous simulator with magnetic interaction models, while also taking account of the ever-changing state of Earth’s own magnetosphere.
